Abstract (en)
[origin: US2011068195A1] A sprinkler for producing a fixed spray pattern includes an inner flow conduit having a nozzle at an outlet. A filter screen is held in place beneath the nozzle. The filter screen engages a push rod of a valve of a flow stop mechanism. The push rod spaces a valve member away from a valve seat to permit water flow through the inner flow conduit when the filter screen and nozzle are in place. If the nozzle is removed or if the inner conduit is severed, the filter screen can be removed, which causes the valve member to close under the force of water pressure and to shut off flow through the inner flow conduit. The valve is located upstream of parts that are vulnerable to damage.
